Meanwhile the smart phone based on iPhone operating systems (iOS) and the smart phone based on Android OS are for example By being based on the positioning, the positioning based on WiFi and the positioning based on honeycomb BS of global positioning system (GPS), in various positioning sides Positioning is executed in case, and provides various LBS based on positioning result.The positioning based on GPS, the positioning based on WiFi is described below With the positioning based on honeycomb BS.
(1) positioning based on GPS
Locating scheme based on GPS includes the positioning based on GPS of the independent locating scheme based on GPS and network assistance Scheme.
First, in the independent locating scheme based on GPS, satellite is used only and executes positioning operation, and passes through detection Multiple satellites (for example, three or more satellites) execute triangulation.Therefore, independent determined based on GPS to use Position scheme, equipment should be from multiple satellite received signals, and according to the signal calculating position coordinate received.
However, the equipment (for example, smart phone) used in current mobile communications network is since power problems are likely difficult to It directly executes and receives the operation of satellite-signal and the operation of calculating position coordinate.Moreover, equipment should be same with multiple GPS satellites Step, i.e., should be locked to multiple GPS satellites to receive satellite-signal, and a few minutes can be spent to carry out initial GPS lock. GPS lock problem may increase actually detected position coordinates the time it takes.
In this case, it has been proposed that a kind of mixed positioning scheme, wherein based on the distance between mobile communication BS Relationship and spread state measurement carry out test position coordinate, and secondly use GPS signal.It is auxiliary that the mixed positioning scheme is referred to as network The locating scheme based on GPS (assisted-GPS, A-GPS) of the locating scheme or auxiliary based on GPS helped.Therefore, it is based on The locating scheme of A-GPS can be minimized test position coordinate the time it takes, while minimize the power consumption of equipment.
2) positioning based on WiFi
Locating scheme based on WiFi includes triangulation and fingerprint recognition.
If using triangulation, device measuring is from multiple AP (for example, three or more AP) received signal The RSS of measurement is converted to distance by received signal strength (received signal strength, RSS), and by with distance The position of related equation detection device.
However, such as decaying, anti-caused by wireless signal experience is by wall, barrier, people in the interior space etc. The multipath transmisstion with diffraction is penetrated, therefore the distance converted may include the relatively large error away from actual range.Therefore, because three The relatively large error of angular measurement usually uses fingerprint recognition indoors.
In fingerprinting scheme, the interior space is divided into relatively small cell, is directly collected from each cell RSS, and database is generated to build radio map by using collected RSS.Equipment is by the RSS received and data Library is compared, and estimates position of the position of the cell with most like signal mode as equipment.Therefore, with radio Network environment becomes more preferable and cell quantity and increases, and fingerprinting scheme can increase positioning accuracy.
Fingerprinting scheme is difficult to use in the region of no WiFi AP, takes relatively long period of time wireless to build Electric map, and consume many costs.In addition, if cause radio map to change due to replacement or the movement of AP, Database should be then regenerated, so as to cause maintenance and maintenance cost.
3) positioning based on honeycomb BS
Locating scheme based on honeycomb BS includes locating scheme and triangulation scheme based on BS ID.
In the locating scheme based on BS ID, equipment detection is connected to the ID of the service BS of equipment.The equipment determines that it is It is no to be connected to BS, the two-way time (round trip time, RTT) between BS and equipment is measured, measured RTT is turned It is changed to distance, and then detects the presence of the equipment in the radius away from service BSXm or Xkm.It can be by the RTT that will measure The light velocity (the time x light velocity=distance) is multiplied by calculate distance.
However, due to can only detect the relative distance relative to service BS in the locating scheme based on BS ID, The locating scheme based on BS ID can not possibly be used in the service for needing absolute coordinate (for example, latitude and longitude).
Meanwhile it can be in the triangulation side using multiple BS (for example, a service BS and two or more neighbor bss) Down link signal or uplink signal are used in case.First, using down link signal, equipment is from its position Set for equipment is that known multiple BS receive signal, and estimate to propagate according to the reception Timing measurement of the signal received Delay.Then, the propagation delay of estimation is sent to location-server by equipment, and location-server prolongs the propagation received Late be converted to distance, and by a distance from conversion relevant equation estimate the coordinate of the position of equipment.Under this use The triangulation scheme of line link is referred to as observing reaching time-difference (observed time in 3GPP LTE standards Difference of arrival, OTDoA) scheme.
In addition, the triangulation scheme using uplink is referred to as uplink time-difference of arrival in 3 gpp (uplink time difference of arrival, UTDoA) scheme.In UTDoA schemes, including service the multiple of BS The propagation delay of estimation is sent to location-server by BS by receiving positioning signal from equipment to estimate propagation delay.It is fixed The propagation delay received from multiple BS is converted to distance by position server, and by a distance from conversion relevant equation estimate to set The coordinate of standby position.
After undergoing multipath transmisstion, it can receive at the entity for executing positioning operation and be determined based on honeycomb BS above-mentioned The signal used in the scheme of position, this may be the main reason for reducing positional accuracy.
Meanwhile the smart phone based on iOS and the smart phone based on Android OS are according to the error model of location information It encloses, position is received with the sequence of the locating scheme based on GPS, the locating scheme based on WiFi and the locating scheme based on honeycomb BS Information.The hybrid plans of these various locating schemes combinations is used not covered by the locating scheme based on GPS The locating scheme based on BS is used in urban area, and is determined using based on WiFi being not received by the indoor of GPS signal Position scheme is possibly realized.
Meanwhile smart phone based on iOS and the smart phone based on Android OS provide various LBS, and for There are various positioning accuracy requests by various LBS.In order to meet various positioning accuracy requests, it may be necessary to high accuracy positioning.It is as follows Face detailed description, this high accuracy positioning be likely difficult to using the locating scheme based on GPS, the locating scheme based on WiFi and It is executed based on the locating scheme of BS.
First, although the locating scheme based on GPS can obtain relatively high precision, for example, the error less than 5m, It needs at least three satellite-signals to support precision.However, the signal from satellite is in the metropolitan district with large amount of building It is blocked in domain (such as intensive urban area) and indoor environment.Therefore, based on the locating scheme of GPS in urban area and room It is infeasible in interior environment.
Secondly, although the locating scheme based on WiFi may realize trueness error in environment indoors, for example, it is less than 5m, But the current accuracy of the locating scheme based on WiFi is for such as [Table 1]In listed indoor navigation LBS be can not Capable.In addition, the locating scheme based on WiFi may not be able to be used in the outdoor environment of no WiFi AP.
Third, the locating scheme based on BS may not be preferred because of its hundreds of meters of errors to several kms.
As described above, the positioning based on GPS, the positioning based on WiFi and based on BS be located in positioning accuracy and use ring There is limitation in terms of border.Therefore, it is necessary to other locating schemes to provide various LBS.
Meanwhile it providing through the positioning based on GPS, the positioning based on WiFi and being located through based on iOS based on BS Smart phone and based on the smart phone of Android OS come provide provide LBS various applications.For the position of detection device It sets or the position of its corresponding equipment, can easily use these applications.
However, what is up to the present proposed is carried by the positioning based on GPS, the positioning based on WiFi and the positioning based on BS Various applications for LBS need user directly to activate corresponding function, i.e. positioning function.For example, in order to receive LBS, user swashs GPS functions, WiFi function and Bluetooth function living, or directly execute corresponding application so that application activating GPS functions, WiFi Function and Bluetooth function.
Therefore, in natural calamity (such as earthquake or tsunami) or the man-made disaster for leading to building collapsing and fossor Under the emergency situations of (fire or building are bad etc.), by the positioning based on GPS, the positioning based on WiFi and based on BS's The various applications that positioning provides LBS may be infeasible.This is because buried person person, which is likely to be at, is difficult to activate corresponding people Situation.In addition, even if corresponding function is activated, the infrastructure of surrounding may also be in the urgent feelings of such as building collapsing It is corrupted such that the positioning based on WiFi becomes impossible under shape.Indoors due to buried person person, the positioning based on GPS It may make impossible.

However, if GPS functions, WiFi function and the Bluetooth function of target D2D equipment are closed or target The user of D2D equipment, which is in user, cannot directly execute the state of corresponding application, then positioning function should activate automatically, without using Intervene at family.Therefore, in embodiment of the disclosure, third party's D2D device activation D2D functions other than target D2D equipment. The detailed description of operation will be provided later, therefore is not provided here.
It is described above according to the embodiment of the present disclosure for detecting target in the communication system for supporting D2D schemes The method of the position of D2D equipment.Now, it is described below according to the embodiment of the present disclosure in the communication system for supporting D2D schemes In by third party's D2D device activation target D2D equipment other than target D2D equipment positioning function method.
According to the embodiment of the present disclosure in the communication system for supporting D2D schemes by other than target D2D equipment The method of the positioning function of third party's D2D device activation target D2D equipment can be divided into two methods, i.e.,:Based on urgent installation Reference D2D equipment by third party's D2D device activation target D2D equipment positioning function method and be based on existing installation Reference D2D equipment by third party's D2D device activation target D2D equipment positioning function method.
First, the reference D2D device broadcasts of urgent installation in the target area find request message.It is set from reference to D2D When for receiving broadcast discovery request message, target D2D equipment sends the discovery response of the discovery request message for receiving Message, the discovery response message include the ID of target D2D equipment.It has sent and has found that the target D2D equipment of response message identifies Target D2D equipment executes the positioning signal needed for positioning operation will be quickly by sending with reference to D2D equipment.It therefore, can be by repairing Change the discovery message defined in current 3GPP TS24.334 to configure discovery request message, to support the reality according to the disclosure Apply the side by positioning function of the third party D2D equipment based on the reference D2D device activation target D2D equipment promptly installed of example Method.
It was found that message can be configured as such as 232 bits.It was found that message includes such as 8 bit message type fields, 184 Bit is based on neighbouring service (ProSe) application code field, 32 bit message integrity checking (message integrity Check, MIC) counter least significant bit (the counter LSB based on the UTC) word of field and the coordination of 8 bits based on generalized time Section.
Message type field includes that 2 bits find that type field, 4 bit spare fields and 2 bits find model field.
In embodiment of the disclosure, it is sent with reference to D2D equipment and finds request message, had and find type field or hair The reserved word segment value of existing model field, is set to indicate that the value that execute urgent D2D positioning operations, to make third party D2D Equipment can be based on the positioning function for the reference D2D device activation target D2D equipment promptly installed.Type is found for example, retaining " 00 " and " 11 " in the value of field.Therefore, in embodiment of the disclosure, if it find that " 00 " in the value of field is set Urgent D2D positioning operations are executed for instruction, then are receiving the discovery request message with the discovery field for being set as " 00 " When, target D2D equipment can activate positioning function.
Meanwhile receive find request message when, target D2D equipment send include target D2D equipment ID (for example, The MAC Address of target D2D equipment) discovery response message.
In another example, the D2D equipment carried from the rescue group for rushing to target area to ProSe application servers or D2D servers send ProSe application code allocation request messages, and request distributes specific ProSe application codes to activate D2D to position Function.
After receiving ProSe application code allocation request messages, specific ProSe is applied generation by ProSe application servers Code distributes to the D2D equipment that the rescue group in target area carries, that is, refers to D2D equipment, and send to reference to D2D equipment ProSe application code assignment response messages include the ProSe application codes of distribution.It is received from ProSe application servers When ProSe application code assignment response messages, it includes that the distribution of ProSe application codes is rung to be broadcasted to target area with reference to D2D equipment Answer the discovery request message for the ProSe application codes that message includes.
When from the discovery request message including ProSe application codes is received with reference to D2D equipment, target D2D equipment hair Send the discovery response message of the ID including target D2D equipment.
Secondly, it is described below for by reference D2D device activation target of the third party D2D equipment based on existing installation The method of the positioning function of D2D equipment.
Once executing application in third party's D2D equipment, the ID of target D2D equipment and the information about target area just pass through ProSe application servers are sent to by PC1 interfaces.Here, PC1 interfaces are ProSe application servers and are mounted in D2D equipment Application between interface.Initially installation is in application, the ID of target device can be registered.
Meanwhile if the ID of target device and the information about target area are sent to ProSe applications via PC1 interfaces Server, then ProSe application servers are in application User ID or the ID and evolution block core (evolved of target device Packet core, EPC) it maps between ProSe User ID, and it is real by PC2 interfaces the ID of mapping to be sent to ProSe functions Body.PC2 interfaces are the interfaces between ProSe application servers and ProSe functional entitys.
ProSe functional entitys generate the specific application code that indicating emergency D2D has found or the automatic activation D2D of request positions work( The specific application code of energy.The application code of generation is sent to via PC3 interfaces and is already installed on shop by ProSe functional entitys In D2D equipment.PC3 interfaces are the interfaces between ProSe functional entitys and D2D equipment.
When receiving specific application code from ProSe functional entitys, D2D equipment (referring to D2D equipment) sends urgent It was found that request message, interrupts the common normal transmissions for finding request message.In order to indicate D2D positioning functions by specific application code Urgent discovery and automatic activation, the discovery type field for finding request message and including can be used, find model field or The reserved word segment value of spare fields, as previously described.
It is described above according to the embodiment of the present disclosure in the communication system for supporting D2D schemes by addition to target The method of the positioning function of third party's D2D device activation target D2D equipment except D2D equipment.Now, it will describe according to this public affairs Open the method for distinguishing target D2D equipment and common D2D equipment in the communication system for supporting D2D schemes of embodiment.
In the method for detecting the position of target D2D equipment based on the reference D2D equipment promptly installed, with reference to D2D equipment All D2D equipment and target D2D equipment of surrounding can receive the discovery request message by being sent with reference to D2D equipment. It is asked that is discovery can also be received by the D2D equipment of onlooker and passerby's carrying in the region near target D2D equipment Seek message.Therefore, it is necessary to distinguish target D2D equipment and common D2D equipment, accurately to detect in target area Realistic objective D2D equipment quantity and the type of D2D equipment that is positioned.For example, it is desired to by target D2D equipment and commonly D2D equipment distinguishes, so as to determine be embedded in the emergency situations such as building collapsing generation region in number and who be Buried person person.
According to the embodiment of the present disclosure for the differentiation target D2D equipment in the communication system for supporting D2D schemes and commonly The method of D2D equipment can be broadly divided into two methods, i.e.,:All D2D equipment are sent for the spy by being sent with reference to D2D equipment Surely find request message discovery response message and with reference to D2D equipment be based on find response message by target D2D equipment with it is general The method and only target D2D equipment is sent for being asked by the specific discovery with reference to the transmission of D2D equipment that logical D2D equipment distinguishes It seeks the discovery response message of message and is based on finding response message by target D2D equipment and common D2D equipment with reference to D2D equipment The method distinguished.
First, all D2D equipment are described below to send for the specific discovery request message by sending with reference to D2D equipment Discovery response message and with reference to D2D equipment be based on find response message target D2D equipment and common D2D equipment are distinguished Method.
The specific discovery request message of reference D2D device broadcasts of urgent installation in the target area, each message include ProSe application codes.When receiving specific discovery request message, all D2D equipment being located in target area execute positioning Operation, and the positioning result value in the discovery response message of the ID including D2D equipment is sent to ProSe application servers.It can To obtain positioning result value by GPS functions, WiFi function, Bluetooth function etc..It is asked that is, specific discovery has been received Ask the D2D equipment of message that the absolute coordinate of D2D equipment is sent to ProSe application clothes by using all available positioning functions Business device.
ProSe application servers will be sent collectively to refer to about the coordinate information of D2D equipment and the map of target area D2D equipment.Then, it is exported by reference to the display of D2D equipment and is believed about the position of all D2D equipment in target area Breath.Therefore, mesh can be identified based on the location information about all D2D equipment in target area with reference to D2D equipment Mark D2D equipment.For example, carrying or management can be based on setting by reference to D2D with reference to the user (for example, rescue group) of D2D equipment The location information about D2D equipment of standby display output distinguishes target D2D equipment and common D2D equipment.
However, because their coordinate information is sent to ProSe application services by all D2D equipment in target area Device, thus all D2D equipment send for by with reference to D2D equipment send specific discovery request message discovery response message, And the method that target D2D equipment is distinguished with common D2D equipment may be caused based on discovery response message with reference to D2D equipment Many signaling overheadss.Moreover, because all D2D equipment in target area all pass through GPS functions, WiFi function and Bluetooth function Positioning operation is executed, therefore this method cannot be used for the disrupted region of infrastructure.
Secondly, only target D2D equipment is described below and sends and disappears for the specific discovery request by being sent with reference to D2D equipment The discovery response message and reference D2D equipment of breath are based on finding response message by target D2D equipment and the common battery limits D2D Separated method.
When receiving specific discovery request message from the urgent reference D2D equipment in target area, D2D equipment Specific discovery request message is exported on its display.For example, if receiving specific discovery request at corresponding D2D equipment Message can then activate pop-up window.For determining that corresponding D2D equipment is the letter of target D2D equipment or common D2D equipment Breath may include in pop-up window.
Simultaneously as some targets D2D equipment possibly can not click pop-up window, so if D2D equipment is receiving Fail to receive the response for pop-up window within a predetermined period of time after specific discovery request message, then D2D equipment can be with Determine that it is target D2D equipment.
It meanwhile in embodiment of the disclosure, can be by the various sensings of such as motion sensor and heart rate sensor Device distinguishes target D2D equipment and common D2D equipment.For example, if being included in the motion sensor in corresponding D2D equipment Detect the general motion pattern of walking, running etc., then D2D equipment does not send the spy for being received from reference D2D equipment Surely the discovery response message of request message is found.On the contrary, if not being general motion by the motor pattern of motion sensor senses Pattern, then the transmission of D2D equipment is for the discovery response message from the specific discovery request message received with reference to D2D equipment.At this In the case of kind, it is found that response message includes the ID of D2D equipment.
In addition, in embodiment of the disclosure, specific discovery request message is received from reference to D2D equipment In D2D equipment, only pop-up window is not responded to special exercise pattern, in predetermined amount of time by motion sensor senses D2D equipment is sent for the specific discovery response message for finding request message.In such situations, it is found that response message includes The ID of D2D equipment.
It is described above according to the embodiment of the present disclosure for distinguishing target in the communication system for supporting D2D schemes The method of D2D equipment and common D2D equipment.Now, by description according to the communication system in support D2D schemes of the embodiment of the present disclosure Specific operation scene in system.It will be provided first using the urgent operation scenario for installing reference D2D equipment in the target area Description.
The reference D2D device broadcasts promptly installed find request message.It can explicitly indicate and find that request message is tight It is anxious to find request message, and be intended to by means of find discovery type field that request message includes, find model field or The reserved word segment values of spare fields is positioned.
On the other hand, the discovery request message for each including specific ProSe application codes can be broadcasted with reference to D2D equipment, And specific ProSe application codes can impliedly indicate that corresponding discovery request message is urgent discovery request message, and It is intended for positioning.Include specific ID by the ProSe application codes sent with reference to D2D equipment.Specific ID can be by for example rescuing Help the ID of the D2D equipment of personnel (such as fireman, police or rescue group) carrying.Specific ID can only be set by the D2D of pre-authorization It is standby to use, and D2D equipment has the priori with the relevant information of specific ID.For example, when D2D equipment is connected to network When, D2D equipment can receive related with specific ID information from network, or can retain in D2D equipment and have with specific ID The information of pass.
When from specific discovery request message is received with reference to D2D equipment, D2D equipment, which is sent, disappears for specific discovery request The discovery response message of breath.Here, it is found that response message can be sent by any D2D equipment or only by target D2D equipment.Together When, find the response message ProSe application codes that include include the ID of corresponding D2D equipment, corresponding D2D equipment ID and By the ProSe application codes sent with reference to D2D equipment, that is, ID is authorized to form specific combination.

It is described above by reference to Fig. 1 automatic in the communication system for supporting D2D schemes according to the embodiment of the present disclosure Detect the exemplary scenario of the position of target D2D equipment.Now, it with reference to figure 2, is described below and is existed according to the embodiment of the present disclosure Automatically the another exemplary scene of the position of target D2D equipment is detected in the communication system of support D2D schemes.
Fig. 2 is to show that detecting target D2D automatically in the communication system for supporting D2D schemes according to the embodiment of the present disclosure sets The schematic diagram of the another exemplary scene of standby position.
Before describing Fig. 2, it is noted that detecting the scene of the position of target D2D equipment shown in Fig. 2 automatically is Detect the scene of the position of target D2D equipment automatically by using the D2D equipment in shop.
With reference to figure 2, the situation for detecting the position of target D2D equipment is if it happens needed, then third party D2D equipment executes tight Anxious position detection application.Emergency location detection application request is deployed in the target area for the position for needing to detect D2D equipment D2D equipment.Therefore, the D2D equipment installed in the target area executes urgent discovery operation, and finds result acquisition based on urgent Location information about target D2D equipment.Target D2D equipment, third party D2D equipment, target area, tight has been described before It is anxious to find operation and emergency location detection application, therefore it is not provided here its detailed description.
It is described above by reference to Fig. 2 automatic in the communication system for supporting D2D schemes according to the embodiment of the present disclosure Detect the another exemplary scene of the position of target D2D equipment.Now, it with reference to Fig. 3, is described below according to the embodiment of the present disclosure Support D2D schemes communication system in discovery request message format.
Fig. 3 is the lattice of the discovery request message in the communication system shown according to the support D2D schemes of the embodiment of the present disclosure The schematic diagram of formula.
Find that the format of request message is activated for automatic according to the embodiment of the present disclosure with reference to figure 3, shown in Fig. 3 D2D promptly has found the format of the discovery request message of operation and D2D positioning operations.
It was found that request message can be configured as such as 232 bit longs, and include message type field, ProSe applications Code field, MIC field and the counter LSB field based on UTC.Message type field can be configured as such as 8 bits, ProSe application code fields can be configured as such as 184 bits, and MIC field can be configured as such as 32 bits, and base Such as 8 bits are can be configured as in the counter LSB field of UTC.
In addition, message type field includes finding type field, spare fields and discovery model field.It was found that type field Can be configured as such as 2 bits, spare fields can be configured as such as 4 bits, and it was found that model field can by with It is set to such as 2 bits.
Meanwhile can indicate corresponding discover whether it is promptly to find by defining new discovery type field.For example, If the corresponding common discovery being the discovery that other than promptly finding, it is found that type field can be set to " 00 " (hair Existing type=00), and if corresponding be the discovery that urgent discovery, it is found that type field could be provided as " 11 " (it was found that class Type=11).
In another example, even if corresponding be the discovery that urgent discovery, needs is promptly had found that it is likely that or may not be needed D2D Positioning operation.The urgent degree of approach for finding to can be only used for determining target D2D equipment of D2D positioning operations is not needed, that is, determine Whether target D2D equipment is located at the accurate location for referring to around D2D equipment, rather than detecting target D2D equipment, such as indicates mesh Mark the latitude of D2D equipment, (X, Y, Z) coordinate of longitude and altitude.Therefore, it if corresponding it is found not to be urgent discovery, sends out Existing type field can be set to " 00 " (it was found that=00).If corresponding be the discovery that the urgent discovery for not needing D2D positioning, Then find that type field can be set to " 01 " (it was found that type=01).If corresponding be the discovery that needs the tight of D2D positioning It is anxious to find, then find that type field can be set to " 11 " (it was found that type=11).
In another example, urgent to find that operation be by find that the format definition of request message is positioned for D2D New discovery model field implement, as shown in Figure 3.For example, if corresponding be the discovery that the urgent hair for not needing D2D positioning It is existing, then find that model field can be set to " 01 " (it was found that model=01), and if corresponding be the discovery that needs D2D fixed The urgent discovery of position, then find that model field could be provided as " 11 " (it was found that model=11).
It in another example, can be by find the format combination new discovery type field and new discovery mould of request message Type-word section carrys out indicating emergency discovery, as shown in Figure 3.That is, if it find that type field is arranged to " 11 " (it was found that type =11), then this instruction corresponding is the discovery that urgent discovery.If it find that type field is arranged to " 11 " and finds model word Section is arranged to " 00 " (it was found that model=00), then this indicates the corresponding urgent discovery for being the discovery that and not needing D2D positioning.If It was found that type field is arranged to " 11 " and finds that model field is arranged to " 11 " (it was found that model=11), then this instruction pair That answers is the discovery that the urgent discovery for needing D2D to position.
On the contrary, can know that instruction is corresponding from the spare fields being included in discovery request message discovers whether it is tight The information that suddenly finds and indicate whether the information for needing D2D to position.For example, two bits in 4 bits of spare fields Bit value in specific bit value can indicate to indicate corresponding discover whether to be the information promptly found and its is spare Specific bit value in the bit value of the another two bit of field can indicate the information for indicating whether to need D2D to position.
On the other hand, the corresponding hair of instruction can be known from the ProSe application codes being included in discovery request message The information for whether being now the information promptly found and indicating whether that D2D is needed to position, this will be discussed in more detail below.
184 bit ProSe application codes include 24 bit public land mobile networks (public land mobile Network, PLMN) ID and 160 bit ProSe application IDs.If ProSe application IDs are used for commercial object, ProSe application IDs Be configured as such as " extensive class of service (rank 0), business subclass (rank 1)/Business Name (rank 2)/.../shop ID (N grades), i.e. dining room business/McDonald/discount certificate/... the branch /Kangnam " form.
Meanwhile it can be by discovering whether promptly to find come configuration instruction is corresponding using ProSe application IDs as follows Information and the information for indicating whether to need D2D positioning.
In the method for the position for detecting target D2D equipment based on the reference D2D equipment promptly installed, ProSe is answered It can be configured as such as " urgent discovery/burial search/whether D2D is positioned/ID/.../emergency region of removing obstacles " with ID.With In based on existing installation reference D2D equipment detect target D2D equipment position method in, ProSe application IDs can by with Be set to for example " whether urgent discovery/missing child search/D2D positioning/Target id/.../emergency area ".
Above-mentioned configuration is only exemplary, it will therefore be apparent that can be by using in the reference promptly installed It is decided through consultation in advance between D2D equipment and target D2D equipment and between the reference D2D equipment and target D2D equipment of existing installation ProSe application IDs configure various ProSe application IDs.
